Antarctic warming

I have undone the addition on Antarctic warming by Phanly. This is for two reasons. Firstly, at present it does not fit into the page well. The Antarctic ice sheet includes the west antarctic ice sheet so a new section is confusing. This is a more general page on ice sheets and it is not at its current state useful to add this sort of detail. Phanly has added this same text to several articles, some where it fits better. Secondly the quality of the addition is poor. The citations/references have no style and need a large amount of work and all four of them (added multiple times and not joined) reference the same study by Eric Steig but in different ways including his biog and a blog. As good as this study is, it is no good throwing in 4 references to try to make it look like some sort of wide consensus when it is really one study. I am not against this addition in wikipedia. In fact I spent some time on the Antarctic Ice Sheet page improving the referencing that Phanly had added. Polargeo ( talk) 08:58, 28 January 2009 (UTC) reply

Thanks Polargeo. I have followed your criticisms and inserted a simple single sentence and copied the Nature reference you greatly improved. Cheers dinghy ( talk) 05:27, 30 January 2009 (UTC) reply

Changed link

I changed the link for "the Weichselian ice sheet". It was previously pointed at http://en.wikipedia.org/wiki/Wisconsin_glaciation which seemed to me to be a mistake. Bj norge ( talk) 18:33, 13 June 2011 (UTC) reply

how can the thickness of an ice shield be measured ?

(in some cases by drilling ;-)

here https://www.nature.com/articles/nclimate2161

footnote 9: repeat stereo satellite imagery

footnote 27 (1997) : satellite radar interferometry

what exactly is it ? How exact are the data obtained with these methods ?

I hope there is an expert ( m / f / d ) who can add a section to the article. thanks in advance ! -- Präziser ( talk) 05:57, 15 June 2022 (UTC) reply

That would indeed be good to add some information on that. You don't need to be an expert either, just have to know how to read the scientific literature on this. :-) I don't have time at the moment, otherwise I would do it. Perhaps there is information about it in the Antarctic ice sheet or Greenland ice sheet articles? Pinging User:InformationToKnowledge, perhaps they know this topic off hand.

Overhaul (December 2023)

I've just reworked this article and have replaced a lot of the content with excerpts. That's because this is a fast moving topic (due to climate change...) and the bulk of the detail sits in the articles on Antarctic ice sheet and Greenland ice sheet. So I think excerpts are the ideal solution here for this article. It's really just an overview article about the two ice sheets on Earth. EMsmile ( talk) 21:43, 20 December 2023 (UTC) reply

One thing to ponder over: should the content about geologic timescales be added to the main text (currently it's only in the lead)? Normally the lead is meant to summarise the content of the main text. EMsmile ( talk) 21:43, 20 December 2023 (UTC) reply
I guess that since you have already excerpted the articles on the current ice sheets, providing excerpts from the articles about historical ice sheets would be reasonable.
As an aside: I see that there are now some contradictions between Greenland ice sheet after my recent edits and the excerpted section on GrIS from effects of climate change. The tricky part is that the latter is based on the 2019 SROCC, which wasn't really featured in the GrIS article at any point. Though the GrIS article now includes a lot of information from newer sources (information, which should be moved to the excerpt as well), I really need to think on how to work at least some of those references to SROCC into the article too, since it remains an important signpost in climate science.
Going back to directly double-check the accuracy of information cited to SROCC and even AR6 might be necessary: i.e. I have some doubts that "The Greenland ice sheet loss is mainly driven by melt from the top. Antarctic ice loss is driven by warm ocean water melting the outlet glaciers." is an accurate summary of what AR6 actually said, since two major papers on Greenland published 1-3 years before AR6 concluded that surface melt is responsible for no more than 33-51%, with outlet glaciers causing the rest.

Regarding the geologic timescales I have now added two excerpts for that. Is "geologic timescales" the best wording? I've seen also "Ancient Earth" and "pre-history" but personally I think I like "geologic timescales" the best. Could also be convinced otherwise though.
Regarding the details from different reports: this would be useful/important to document and reconcile but I can imagine that it can be quite fiddly / detective work. Would be good to have additional people to help with that, maybe even experts in the field who have all that knowledge at their fingertips. EMsmile ( talk) 10:38, 22 December 2023 (UTC) reply
